16 Port Switch Question

On this unit, port #16 is labeled the uplink, and this connection connects to the router which then connects to the cable modem.

For two days, there has been no internet connectivity, but local folders on the network are accessible. I suspected the router was the problem but I could not connect to it via the web or ping it.

I unhooked the router and connected it directly to a computer. I was then able to connect to it via the web (http://192.168.1.1). I then reconnected the router to the switch, checked the cables and changed them around to make sure it was not a faulty cable, but I was still unable to ping the router.

Is it possible that port #16 is bad? Can I connect the switch and the router via another port, aside from #16?
